Title:
NOISE SHAPER
Document Type and Number:
Japanese Patent JP3042201
Kind Code:
B2
Abstract:
PURPOSE: To make an output signal zero in the case a non signal is inputted without deteriorating the S/N characteristic of the noise shaper.
CONSTITUTION: The noise shaper consisting of integration circuits S1 and S2 more than one stage, ternary quantization device C outputting 0 and ±1, and feedback circuit including a delay device D detects consecutive zero input signals of the noise shaper. A control circuit C0NT is provided which forcedly makes the output signal of the noise shaper zero according to the successive circuit of the zero input signal.
